KILN.

It is the primary purpose of invention to produce a kiln structureembodying an improved arrangement of the heat distributing fines orpassages whereby the heat and products of combustion are admitted above,as well as below'the kiln floor so that the'brick or tile within thefurnace will be uniformly burned. 1

The invention has for an additional object to provide a kiln which maybe economically operated, and in which the heat is most effectivelyutilized so that the time necessary for the proper burning of theclay isreduced to a minimum. a

With the above and other objects in view, my invention consists in thenovel features of construction, combination, and arrangement of parts tobe hereinafter more fully described, claimed, and illustrated in theaccompanying drawings,-in which,

Figure l is a side elevation of a kiln embodying the preferred form ofmy invention;'Fig. 2 is a vertical section; Fig. 3 is a horizontalsection taken on the line 3-3 of Fig. 2; and Fig. at is a section takenon the line H of Fig. 3.

Referring in detail to the drawings, designates the base or foundationupon which the kiln structure is built. This kiln structure includes thevertical body wall which, in the illustrated form of the invention, iscircular and provided with an arched dome 6. Upon the base 5, within thecircular body wall of the kiln,v a series of parallel vertical walls?are built, said walls being spaced from eachother and constitutingleaders for the products of combustion, which are admitted into saidspaces in the manner to be hereinafter explained. Each of these walls isprovided with a multiplicity of openings indicated at 8.

Exteriorlv of the kiln wall 6, andv upon opposite sides thereof, thefurnaces, generally indicated by the numeral 9, are built,

Specification of Letters Eatent.

four such furnaces being preferably employed 1n each series, although itis obvious that a greater or less number of such furnaces may be used,in accordance with the desired. capacity of the kiln. Each furnace islocated directly opposite to an inlet opening 10 in the wall 6 of thekiln and beneath each furnace grate, an ash pit 11 is formed.

Upon the vertical lead walls 7, the floor 12 of the kiln'is built, saidfloor consisting of a plurality ofrows of fire brick, the bricks in eachrow being spaced apart and resting at their ends'upon the upper edges ofthe.

adjacent walls 7. Thus, a plurality of ver-' tical passages is producedbetween these floor bricks, which communicate with the spaces betweenthe lead walls7, thusadmitting the products of combustion to theinterior of the kiln. Upon each sideof the Patented Mar. 14, 1916.

Application filed January 6, H315. Serial No. 849. V Y V kiln andcontiguous to the series of furnaces,

the fire bricks 12 are arranged compactly or in contact with each other,as this point of entrance from the furnaces into the lead passagesbeneath the floor,'is subjected to'a very intenseheat. V V

'Vertical fines 13 are built upon the inner face of the kiln wall 5, andcommunicate at their lower ends with the alternate furnaces 9 of'eachseries. These flues open at their upper; ends a considerable distanceabove the floor 12 and adjacent to the arched dome of the kiln. Fourchimneys 14: are also.

provided, said chimneys being arrangedin pairs between the two series offurnaces, and each chimney having two outlet fines with which openingsin the kiln wall,indicated at 15, communicate, said openings being 10cated adjacent to the top of the kiln. Each of the chimneys is providedwith a suitable damper plate 16 whereby the outlet of the hot air fromthe interior of the furnace, may be cut off, when desired; The verticalbody wall of the kiln is provided with a suitable door, indicated at 17,through which access may be conveniently had to the interiorthereof. Itis, however, to be understood that, if desired, the inlet opening maybeformed in the dome of the kiln.

From the foregoing description, it is be-. vlieved that the manner ofconstructlon, as

well as the several advantages of my in.

proved kiln, will be fully and clearly understood. The proper fuel isplaced in the sev eral furnaces and successively fired. The

heat and products of combustion are admitted from the pair of furnacesin each series into the lead passages beneath the kiln floor and thenpass upwardly against the lower tiers of clay tile or brickarranged uponthe kiln floor. The products of combustion from.

the damper plates 16 in the chimney flues,

to a greater or less extent. 7 In this manner, I reduce the consumptionof fuel, and thus effect a material economy in the operation of thekiln, and also obtain better results in the burning of the tile orbrick, and reduce the time of operation to a minimum. These severaladvantages obtained from my improved kiln structure, are of primaryimportance.

While I have shown and described the preferred construction andarrangement of the several features of my improved kiln, it will beunderstood that the same are susceptible of considerable modificationand I, therefore, reserve the privilege of resorting to all suchlegitimate changes as may be fairly embodied within the spirit and scopeof the invention as claimed.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is In a kiln, a solid base wall, a verticalbody wall built thereon, a solid dome mounted on the bodywall, aplurality of spaced vertical walls built upon said base within the kilnand providing upwardly directing heat leads, each of said walls having aplurality of openings therein, said openings being an ranged inalinement to provide direct heat,

aassa 'es communicatin with the first heat leads, floor tile arrangedupon the upper edge of said walls in spaced parallel IOWs and providinga multiplicity of openings communicating with the upwardly directingends with the remaining furnaces, said fines,

opening into the kiln above the floor thereof and at a point adjacentthe top of the body wall, a plurality of chimneys on opposite sides ofthe body wall of the kiln between the two series of furnaces andcommunicating with the interior of the kiln above said floor;

and a damper arranged within each of said chimneys for controlling theoutlet of hot;

air from the interior of the furnace.

In testimony whereof I hereunto my signature in the presence of twowitnesses.
